Address and send traditional snail mail via email on the cheap with web site Postful. In contrast to a similar service called eSnailer, which sends snail mail for free but requires you to sign up for a "special offer," Postful asks for a relatively low fee of $.99 for the first page and $.25 for each additional page. Whether it's to keep in contact with a Luddite lacking an email address or you just really hate buying stamps and finding a mailbox, Postful is a potentially worthwhile tool. You can even set up unique Postful email addresses for frequent contacts so that, for example, you can include your email-less grandparents in an email you're sending.
